Unable to restore from backup of a newer device
I am unable to restore from backup of a newer device, and it says the solution is to update your device to the latest version of iOS to be able to restore the backup, but how do I do that without first setting up the iPhone?
Im upgrading from an iPhone 5S running iOS 8.3 to an iPhone 6+ running iOS 8.2. Its a brand new 6+, so I can't upgrade it until I complete the setup process, but I can't complete that without restoring from an iCloud backup.
